Aryl hydrocarbon receptor deficiency leads to sex- and age-dependent colonic dysmotility in miceNARA Subscribed
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor involved in xenobiotic sensing and multiple physiological functions, including intestinal homeostasis. Aging is associated with reduced colonic motility and constipation, but the contribution of AhR to intestinal motor function across sex and age remains incompletely defined. We performed a phenotypic characterization of AhR-deficient (AhR −/− ) and...
The common octopus is the most commercially important cephalopod species in the Mediterranean and Northeast Atlantic. In recent years, changes in population dynamics associated with climate warming have been observed, including migration to northern waters and alterations in the timing and duration of the reproductive period. These variations underscore the necessity of regularly updating the biological parameters for effectiv...
The thornback ray, Raja clavata Linnaeus, 1758, is the most commonly landed batoid species in bottom trawl fisheries of the Balearic Islands. Its commercial importance has led to unsustainable exploitation in recent decades, potentially threatening population stability. This study aims to estimate key biological and ecological parameters of this species in the Balearic Islands, including bathymetric distribution, reproduction,...
Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of StatolithsNARA Subscribed
We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and Mediterranean Sea during 2021–2022 were analysed using laser ablation ICP‐MS to measur...
A balanced approach to the potential of octopus aquacultureNARA Subscribed
Insight into the biology, ecology and population trends of the brown skate, Raja miraletus Linnaeus, 1758, in the Balearic IslandsNARA Subscribed
We studied the life‐history traits of the brown skate ( Raja miraletus ) population off the Balearic Islands, which is a species commonly caught as bycatch by the bottom trawl fishery in the Western Mediterranean. Samples and data were collected year‐round from commercial catches and yearly during spring–summer from the International Bottom Trawl Survey in the Mediterranean. The maximum total length observed was 43 cm, consist...
Physical activity and hippocampal volume in young adultsNARA Subscribed
Evidence from previous studies suggests that physical activity (PA) may contribute to functional and structural changes in the hippocampus throughout the lifespan. However, there is limited evidence available regarding the young adult population. Additionally, the personality traits that may influence this association remain unclear. With a sample of 84 young adults (43 women; age 22.7 ± 2.8y; range 18–29), the main aim of the...
Stock discrimination of two European squids ( Illex coindetii , Loligo forbesii ) by statolith shape analysisNARA Subscribed
We evaluated the feasibility of classifying ommastrephid and loliginid squid species by statolith shape analysis into fisheries management units or stocks. Statoliths of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) were studied from multiple areas of the North East Atlantic and Northern Mediterranean Sea during 2021–2022. I. coindetii and L. forbesii individuals were categorized into multiple stocks ac...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
The Spanish bottom trawl fleet operating in the Mediterranean currently uses 40 mm square mesh codends. Its selectivity is still too low to overcome the overall problem of high proportions of immature specimens in the catches. Even for some target species such as the European hake ( Merluccius merluccius ), there are high proportions of individuals smaller than the minimum conservation reference size (MCRS). The aim of the pre...
This study provides the first socio-ecological overview of the Seriola dumerili fishery occurring in the Balearic Islands. This pelagic top-predator is among the five most valued fish resources of the Balearic community. Despite its ecological importance and potential vulnerability to aggregation fishing, few studies address the ecology of this large Carangidae species. Shining a light on its ecology is vital to ensure adequat...
